ABSTRACT
BACKGROUND:
Pulsed field ablation (PFA) is a novel method of non-thermal cardiac ablation for atrial fibrillation (AF). Its use on patients with pre-existing Watchman devices has not been studied.METHODS:
Pulmonary vein isolation (PVI) utilizing PFA was performed in 7 patients with symptomatic AF and implanted Watchman devices. All cases were conducted at a single academic center.RESULTS:
Successful PVI in patients with Watchman devices implanted at a median time of 534 days prior to the index ablation procedure (IQR 365 days) was achieved in all cases. No major adverse events (intraprocedural CVA, post-procedural CVA, major or minor bleeding events, device embolization, or cardiac tamponade) were observed. In 6 of 7 patients, a low-dose direct oral anticoagulant (DOAC) strategy was implemented post-PFA.CONCLUSION:
We present the first reported case series of PFA in patients with AF and implanted Watchman devices. This study highlights the safety and feasibility of the FARAPULSE PFA system in this patient population.
